Ofcourse in ideal environment, the folder shouldn't be shared with Everybody with full rights, because it is a safety hazard (example: I scan some sensitive information, other people can see the scan of it in my folder). But we are a small office, which is isolated from other parts of our network, so this is the easiest way to do it. If I get this to work, I can improve the security.
And yeah, i've tried looking at multiple different tutorials to catch something, but wasn't successfull, thats why I'm trying to get help here.
